Since so many trout died, we started counting how many were alive instead.

2008 - 2009 TANK UPDATE - TERRIBLE CRASH!

Tuesday 4/7/09 I checked the tank and all was fine - the tomatoes hadn't germinated but the lettuce had. I remembered that the tomatoes like to germinate at 70 degrees F so raised the chiller temp from its old setting to 68.5 F.

Wednesday 4/8/09 I check the room at 7:00 pm and found a pile of dead fish - so many that the filter was clogged with them. I also noticed the bubbler was completely eroded through so I figured with the high water temp the DO was to low and the fish were suffocating. The dead looked fine - no bite marks are fungus. I removed 58 dead trout from the tank and rushed off to buy a new air stone. The fish that were still alive were at the surface of the tank gulping water.

When I came back 12 more were dead - raising the total dead to 70. The dead ones all had their mouths open like they were gulping for air. I had left some weak ones in the tank, hoping they would survive until I replaced the air stone but they didn't. I replaced the air stone and took the following measurements:

• DO - 2 ppm
• NH3 - 7.5 ppm
• pH - 6.2

The NH3 and pH were at their maximum readings. I tested the pH of the tap to be sure the test kit worked and it tested at 6.8 - seemed reasonable. So I diluted the next tank testing to 50% and retested the pH - it read 7.2 so I think the 6.2 reading was accurate.

I dropped the chiller temp back down to 63 F.

Thursday 4/9 8:30 am. All 14 fish survived the night. I tested the DO and it measured 8 ppm.The chiller registerd 59 F although it was set at 63 F. That was low so I measured the water temp - it read it read 58 F. So I raised the chiller to 65F. Two tomatoes germinated.

I flushed the tank to 50% and added 2 drops of chloramine stabilizer. I took the following tank measurements after the flushing:

• NH3 5.0 ppm
• pH 6.4

I fed the fish and they looked fine.

HYDROPONICS

Emily 4.5.11


Hydroponics is pretty much the growing of plants without the use of soil, but water instead. Hydroponics has been used for growing plants all throughout history. Ancient Egyptian hieroglyphics suggest that growing plants on water was a popular way to cultivate crops. Other examples of hydroponics used in history are the hanging gardens of Babylon and the floating gardens of the Aztecs in Mexico. Hydroponic plants just like land plants need light, oxygen, and carbon dioxide, and the root systems require water, nutrients and oxygen. The water and nutrients are taken up by the roots. Then soil drainage allows water to be replaced by air in the gaps between soil grains. In hydroponics the nutrients dissolve in the water. The soil can be replaced with a growth medium to supply the roots with water or you could use a nutrient solution called hydro juice. Both methods need a pump and timer to circulate the nutrients through the roots.

The seed I recommend is the Rex lettuce. It is the most resistant to high temperatures. The root temperature should be between 21 degrees Celsius to 32 degrees. In order to germinate lettuce requires cooler temperatures, it can be placed in an environment of 4 degrees Celsius for one to two days. Once they begin to crack and grow they must be placed in temperatures between 15-18 degrees Celsius.



The most popular plants that are grown hydroponically are lettuce and tomatoes.

HYDROPONICS: SEED RECOMMENDATION

Frantz TCA 4/4/11
The plant that I recommend for our class in the trout expirement is a plant called Elodea. Elodea is a seaweed type of plant that works in almost every type of temperature.It is native to North America,South America and Africa it also reffered to as the waterweed. It is highly recommeded for classroom marine life. Elodea can be purchased in local pet shops and is very easy to acquire.The other plant that i am suggesting to the class is tomatoes they also show very good growth rates using hydroponics.

CLASSROOM PROJECT

In order to do our classroom project we need the 2 plants called the lettuces and tomatoes. First we need to put the lettuces and tomatoes
on the Styrofoam. Second we put the Styrofoam with tomatoes and lettuces on the top of the water on the tank. The second we put the
UV light for the plants to photosynthesize. The third we have to wait for the plants to grow.
